DEODORIZER Filed Jan. 2, 1937 respect to the other part.

Patented Nov. 9, 1937 UNETED STATES DEODORIZER Joseph Dempster Keillor, Aylmer, Ontario,

Canada Application January 2,

11 Claims.

The invention relates to a deodorizer for attachment to a ush tank of a closet in order to disseminate a disinfectant in conjunction with the flushing of the closet;

The invention comprehends a simple and reliable attachment for a closet whereby a toilet room may be kept in a disinfected or perfumed condition. A distinctive feature of construction resides in the provision for regulating the amount of the disinfectant material diffused.

The invention essentially consists of an openended cylinder positioned vertically in the flush tank with its lower end submerged in the water in the filled condition of the tank. Within the top portion of the cylinder is seated a disinfectant chemical compound in the form of a cake or solid mass. The compound is composed of well known ingredients which are for the purpose of this invention combined into a loosely packed cake or brick that dis-integrates of its own volatility when exposed to air.

The cake or brick is made a less width than the bore of the cylinder to provide a circumferential air passage leading to a storage chamber formed by a lower portion of the cylinder. Discharge openings enable the vaporized disinfectant to p-ass into the tank. These discharge openings are controlled by constructing the cylinder in two parts so that one part may be turned with To compensate for disintegration of the cake of disinfectant it is elevated by a float mechanism.

Referring to the drawing: Figure l is a Vertical sectional elevation of the deodorizer.

Figure 2 is a top plan thereof.

Figure 3 is a fragmentary vertical section depicting the junction of the two parts of the cylinder, which parts are shown Separated.

Figure 4 is a vertical view of the float mechanism.

Like numerals of reference indicate corresponding parts in each of the figures throughout the drawing of the invention.

The practical embodiment of the invention herein illustrated, comprises a cylinder composed of a top part 5 and a bottom part 6. The top part is open at both ends and contains the cake or brick of disinfectant I which is of sufficiently less diameter to provide a circumferential air passage 8.

'I'he cake is seated on an imperforate tray 9 rigidly mounted on the central vertical rod I of which a portion I I projects above the tray and is lodged in a hole in the bottom of the cake to preclude its displacement. The portion of 1937, serial No. 118,767v

(ol. izzsy Y the rod below the tray iswvertically slidable in a sleeve I2 forming aguide therefor, of which the top serves as a rest for the tray in order to sustain the cake at such an` elevation that its top portion protrudes slightly above the upper edge I3 of the container 5 aforementioned.

The sleeve I2 is carried by the lower end of the said container. For this purpose it is preferred to employ a horizontal perforated plate I4 suitably united to the lower portion of the container. The perforatons I5 place the container in communication with the bottom partV 6 of the cylinder which forms the storage chamber'for vaporized disinfectant.

The cylinder is vertically suspended in a conventional flush tank at such an elevation that the bottom part 6 that forms the storage chamber is partly immersed in the water to a depth as is indicated by the broken line I6 in Figure l. The means employed to suspend the cylinder may and Will preferablyvtake the form of a hanger strap Il rigidly secured to the container 5; other means, however, may obviously be substituted without departing from the spirit and scope of the invention.' y

The storage chamber 6 is open at both ends and the upper end' I8 thereof is fitted over the lower end of the container and is of a ioose t so as to permit'it to .be turned about the same. Retaining means are shown-at I9 to preclude displacement ofthe intertting portions of the container and the storage tank, which means consist of interlocked circumferential beads formed at the junction of these parts.

Correspondingly spaced holes 2D are supplied in the Walls of both the container and the storage tank, which holes are located between the tray 9 and the plate I4. By turning the storage tank the discharge passages provided by the holes may be reduced so as to regulate emission of vaporized disinfectant.

The purpose of making the rod II) slidable is so that it may be elevated by a float 2l, which is depicted as an inverted cone-shaped member guided in the lower end of the storage tank and rendered buoyant by entrap-ped air as will be Well understood.

In the use of the deodorizer, as the chemical cake vaporizes the vapor laden air in the surrounding passage descends to the storage chamber therebelow and is dischargeed into the tank by the outlets 20. This discharge is promoted in the flushing of the| tank by the rise of water in the lower end of the storage chamber. When the cake is reduced in bulk by evaporation and thus becomes lighter in weight, the float elevates the tray and thus raises the remainder of the cake to the topof the container. In this manner disintegration is automatically compensated.

What I claim isz- 1. A deodorizer comprising a hollow cylinder vertically arranged and having an open upper end, an imperforate tray horizontally supported therein circumposed by a vapor passage, said tray being adapted to seat a chemicall compound for which the surrounding cylinderforms a container having an intervening air passage in`f communication with the aforementioned vapor @"slidable manner, and a float lodged in the cylinpassage, and means providing for lateral diffusionA of vapor from the cylinder.

2. A'deodorizer comprising a hollowcylinder vertically arranged and having open ends, an imperforate tray horizontally supported therein circumposed by a vapor'passage, a chemical compound seated on the tray and spaced 'from the cylinder by an intervening air passage in communication with the vapor passage aforementioned, and'means providing for lateral diiusion of vapor below the said vapor passage.

3. A deodorizer comprising a hollow cylinder vertically arranged and having open ends, an imperforate tray horizontally supported therein substantially below the top thereof, said tray being adapted to seat a chemical compound for which the portion ofthe cylinder therearound forms a container with an intervening air passage in communication'with the aforementioned vapor passage and the portion of the cylinderV below the tray forms a storage chamber, said' cylinder having lateral openings in its storage-chamber portion for the discharge of vapor.

4. A deodorizercomprising a hollow cylinder vertically arranged and havingY open ends, animperforate tray horizontally supported therein substantially below the top thereof, said tray being adapted to seat a chemical compound for which the portion of the cylinder therearound formsha container with an intervening air passage in communication with the aforementioned vapor passage and the portion of the cylinderbelow the tray forms a storage chamber, said cylinder'hav-l ing lateral openings in its storage-chamber portion for the discharge of vapor, and means-for controlling said openings. V A

5. A deodorizer in accordance Ywith claim 1, in which means are provided-,to-elevate the seat to compensate for evaporation of the chemical compound.

6. In a deodorizer, a supporting unit, a tray vertically slidable therein, and a iioat attached to the tray to control the elevation thereof.

7. In a deodorizer, a supporting unit, a tray disposed therein for vertical movement, a depending rod carrying the tray and slidably mounted in said supporting unit, and a float attached to the lower end ofthe rod.

8. In a, deodorizer, a cylinder having open vvends, a tray disposed therein for vertical movenient, means for supporting the tray in a vertically der and carried'by the tray.'` V
